IMPROVED WAGON-BRAKE.

The Schedule referred to :ln these Letters Patent and making part ot: the same To whom it may concerne. v

Be it known that I, WILLIAM .'I. WARD, of Indianapolis, in the county of Marion, and State of Indiana, have, as I believe, invented new and useful Improvements in Brakes for Wagons and other vehicles;' and I .do hereby declare the bllowing to be a full and eX- aet description of the saine, reference being had to the drawings that accompany and form a part of these tion uponthe rubbers F, will insure certainty of acspeciiications.

Figure 1, plan view of the running gear of a wagon. Figure 2, sectional view, showing position of parts when the brake is relieved om the wheel.

Letter A, the axles. Letter B, connecting-bar. Letter C, braces. Letter D, cross-bar for the brak Letter E, journals in which the bar D rests.

Letter F, cams on the bar D.

Letter G, two short levers extending rearward from i the bar D. Y

Letter H, Vweights on the rear ends of these levers Gyas in the drawings.

Letter I, lchain extending from a staple in the centre of the bar D7 as in iig. 1, forward to the evener I or draughtbar.

Letter J, evener, to the ends of which the Whiiletrees are to be attached.

Letter K, staple in the evener, to which is attachedy the chain I.

Letter L, an iron strap, so formed as, when attached to the rear of the pole, to form a slot,- m, as in iig. 2.

n n, two holes, in which is used the pin O, for purposes hereinafter more fully explained.

My invention consistsin the application of weight or weights H, which will, when left free, by the force of gravity keep the rubbers or cams F pressed against the wheels, as in iig. 1, and in so connecting the bar D with the draught of the team, that, when force is applied for locomotion, the rod .or bar D shallV be rotated by means of the. chain I, andthe wheels relieved .from the friction-cams. vhen the wagon moves forward, the position 'of the parts will be as represented in fig'. 2, and the wheels" free. In descending a grade, when tension isl taken off the chain I, the weights H bring the bar D to position indicated in fig. 1. v

7 The-constant action of the weights H, and the friction.

` If one wishes to leave his team standing awhile, he can chain the wheels, simply by changing the pin O from the front to the rear hole n, vand then, should the team attempt to move forward, the Ichain I will not straighten, vconsequentlythe cams will remain against the wheels sothey cannot rotate freely.

Upon roads where there is but slight descent,and no friction required, the pin O may be placed behind the evener J, and then the weights H will be kept raised, and the cams free from the wheels.

In backing the Wagon'no attention to the brake is required, as the reverse motioniof the wheel does not bring the cams or rubbers into action, but relieves them.

What I claim as of my invention, and desire to secure by Letters Patent, is

1. The application of one 4 or more weights'H, ,by Whose specificA gravity the cams or rubbers F are kept to the periphery of the wheels, substantially inthe manner and for 'the purposes speciiied.

2. The strap L, provided with the holes n u, and bolt or pin O, as and for the purposesset forth.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses. T. WARD.
